WebDec 2, 2010 · The present study deals with the mechanistic reaction pathway of the α-dicarbonyl compound methylglyoxal with the guanidino group of arginine. Eight products were formed from the reaction of methylglyoxal with Nα - tert -butoxycarbonyl (Boc)-arginine under physiological conditions (pH 7.4 and 37 °C). WebThe "classical" Merrifield method was used to synthesize over 500 peptides using Boc-benzyl strategy. The peptides were prepared either manually or on a Beckman 990B synthesizer or an Applied Biosystems 430A synthesizer. Each coupling of Boc amino acid to the growing peptide on the resin was monitored with the ninhydrin reaction.
